anism for use on typewriting machines, and

comprises improved means for selectively setting column stops to operative position,

and for returning the stops to inoperative position.

The traveling carriage may have a rack bar mounted thereon carrying a series of column stops at letter-space intervals, said stops selectively movable into and out of the path of cooperating key-set counterstops. The rack bar may comprise vertical rack teeth on its front and rear faces for positioning and guiding the stops thereon, which stops may be yieldingly held up ininoperative position by spring detents connected to the stops and projecting over the upper surface of the rack bar, said stops movable downwardly and held in operative position by said detents en aging notches'in the adjacent rack teeth.

The stops on the rack bar may be selectively set to operative position by a stopsett-ing blade extending over the rack bar and movable downwardly to force downward to operative position. any column stop brought beneath the blade. Said blade may be formed with a stem vertically guided and supported in a bracket, which may be mounted on the machine frame. Said blade may be depressed by means of an integral finger-piece to set any column stop when the carriage has been brought to the columnar position-controlled by said stop. The stopsetting blade may be returned by a coil spring.

The column stops may be returned to inoperative position. by a resetting cam movable forwardly into the path of the stops. Said cam may be formed integral with a rearwardly projecting stem slidably mounted in the bracket and provided with a fingar-piece for moving the cam forwardly to operative position beneath the stops, the cam beingspring returned. hen the re setting" cam is inoperative position, the can rlage may be moved from left to ri ht, causmg the projected stops to successively en.- gage the cam and thus be forced upwardly to inoperative position,

Other features and advantages Will here- I inafter appear. In the accompanying drawings, Figure 1 1s a rear perspective view of the tahulating mechanism as combined with an Underwood typewriting machine. 1 1g. 2 is a sectional elevation showing a column stop and the stop-setting blade in noperative position,

Fig. 5 is a view of the same parts, but with the resetting device moved to operative position and showing a stop reset thereby.

F 1g. 6 1s a perspective view of a stop.

The rack bar 1 may be mounted on the usual traveling carriage 2, the letterdeed travel of the latter being controlled by the usual letter-feed mechanism (not shown). Vertical rack teeth 3 and 4 on the front and rear faces of the rack bar are positioned at letter-space intervals and serve to position and guide a series of column stops 5. These stops 5 are preferably placedat letter-space intervalsthroughout the entire length of the rack-bar, but for the sake of clearness of illustration some of the, stops have been omitted Each stop 5 preferably comprises front and rear vertical arms 6 and 7 guided between the rack teeth and 4, and a hori zontal connecting yoke or arm 8 located beneath the rack bar. Each stop 5 be yieldingly held on the rack bar in either inoperative or operative position by means of ,a spring detent 9-, which, when the stop is in its upper or inoperative position, hooks over the upper face ofthe rack (l igsf2- and 5), and when the stop is lowered to operative position (Figs' and i) said'detent engages a'notch 10 in the jacentrack tooth 3.

The stops 5, when lowered as in the'l ig. position, are adapted to cooperate with a se ries of counter-stops 11, which may be progecte'd into the path of the column stops" .5 by

keys 12 on key levers-13 extending beneath the counter-stops-11.- These counter-stops, 5 which are shown as vertical bars mounted in a stationary frame 14, form a series of denominational or decimal stops selectively operable to arrest the carriage at any decimal position in a column whose location is determined by;.{ the stop 5 with which the counter-stop ed crates. This operation is wellunderstoo' the. art and need not be .further, de jIt may be noted, however, that {stops 11 are prefer ably-provid' thmeans (not shbwn) for releasing the carriage from the letter-feed mechanism when a counter-stop is lifted, permitting the carriage to run forward until arrested by a column stop 5 striking the projected counter-stop 11.

The-stops 5 are set lay-means of a stop-setting blade 15, which extends forwardly over the rack "1, said blade formed integral with a stem 16 ver tioally, supported and guided in'a' bracket 17, which -may be secured by screws 18 to the rear face of the frame 1 1. When it is.

desired to set a stop 5 for arresting the'car- .riage at'any columnar position, the carriage is brought to said position and the blade is depressed by means of an'integral fingerpiece 19, and thereby forces downwardly the stop 5 corresponding-"to said position, the stop'being moved from the Fig. 2 position to the Fig. 8 position.

The blade 15, when released, is returned by a spring 20, which may be coiled around the stem 16, and is confined between a lug 22011 the bracket 17 and a stop pin 23 on so the stem 16, said stoppin also limiting the upward'movement of the blade 15 by engaging a guiding lug 2 1 on thebracket 17. The downward movement of the blade 15 is limited by a shoulder 25 thereon, which s5 strikes the bracket 17 when the stop 5 has I been lowered to such position that the detent 9 can seat in the notch 10. Any desired stops 5 can thus be set, depending upon the rulings of the work-sheet or the nature of the particular piece of work in connection with. which the tabulating mechanism is being used. v

Thestops 5 may .be reset to inoperative position by a resetting cam 26, which may be formed into ral with a rearwardly proiecting stem 2 slidably mounted in the bracket 17, and movable forwardly to bring the cam 26 beneath the;rack 1. Thecam having beenmoved forwardly, as bymeans of a finger-piece 28 to the Fig. 5;posit'ion,

the carriageis moved to the right, and the projected stops are thus successively brought into engagement withithe cam ;26- andcamiiied -upwardlyto the F g. 5 position the, detects 2?: initil where theyi iagre held by spring 29 I movement of the resetting cam is limited in to operative position.

again set by the blade 15. 'Iheca'm 26 may be returned toinoperative position by a coil mounted on the stem '27. The

both directions by the bracket 17 as indicated in Figs. 4 and 5.
